Computer-implemented methods and systems for categorizing a uniform resource locator (URL) based on web content associated with the URL are disclosed. In one aspect, a method includes identifying a first URL using a first URL collection method, assigning, using an electronic processor, a first categorization priority to the first URL based on the first URL being identified using the first URL collection method, categorizing, the first URL based on the first categorization priority, identifying a second URL using a second URL collection method, assigning, using an electronic processor, a second categorization priority different than the first categorization priority based on the second URL having been identified using the second URL collection method; and categorizing, using an electronic processor, the second URL based on the second categorization priority.

System and method of analyzing web content

A system and computer based method are provided for identifying active content in websites on a network. In one aspects, a method for classifying web content includes determining a first property associated with static content of a web page, determining a second property associated with the content of the web page based at least in part on active content associated with the web page, evaluating a logical expression relating the first property and the second property, at least in part by evaluating whether a constant value matches at least a portion of the content of the web page, associating the web page with a category based on a result of the evaluation, and determining whether to allow network access to the web page based on the category.

System and method for analyzing web content

A system and method are provided for identifying active content in websites on a network. One embodiment includes a method of classifying web addresses. One embodiment may include a method of generating a score indicative of the reputation, or likelihood that a web site associated with an uncategorized URL contains active or other targeted content based on an analysis of the URL. In certain embodiments, the score is determined solely from the URL string. Other embodiments include systems configured to perform such methods.

System and method of analyzing web addresses

A system and computer based method are provided for identifying active content in websites on a network. One embodiment includes a computer based method of classifying web content. The method receives content of a web page, and determines a first property associated with the content, the first property including static content. The method executes active content associated with the webpage, and determines a second property associated with the content based at least in part on the executing, the second property including the active content. The method also evaluates a logical expression relating the first property and the second property, and associates the web page with a category based on a result of the evaluation. The evaluation of the logical expression at least in part evaluates whether a constant value matches at least a portion of the content of the web page.

A system and method are provided for identifying inappropriate content in websites on a network. Unrecognized uniform resource locators (URLs) or other web content are accessed by workstations and are identified as possibly having malicious content. The URLs or web content may be preprocessed within a gateway server module or some other software module to collect additional information related to the URLs. The URLs may be scanned for known attack signatures, and if any are found, they may be tagged as candidate URLs in need of further analysis by a classification module.

A system and method are provided for identifying active content in websites on a network. One embodiment includes a method of classifying web content. In one embodiment, the classifications are indicative of active and/or malicious content. The method includes identifying properties associated with the web page based at least partly on the content of the web page and storing said properties in a database of web page properties. The method further includes comparing at least one definition to properties stored in the database of web page properties and identifying the web page with at least one definition based on comparing said definition with said stored properties. The method further includes identifying the web page with at least one category associated with the at least one definition, wherein said category is indicative of active content associated with the web page. Other embodiments include systems configured to perform such methods.

Certain embodiments provide for systems and methods of monitoring data sent from a requested device to a requesting device and removing certain portions of the data such as malicious or otherwise objectionable content. Objectionable content may include, for example, potentially executable web content. In certain embodiments, the systems and methods remove uniform resource locator (URL) links from the intercepted data which point to web pages having malicious or otherwise objectionable content.
